Question

Calculating Rate of change

Answer 1

Answer/Step-by-step explanation:

We are given the following coordinates of two points on the line of the graph shown in the question as: A(2, 1) and B(4, 2)

Vertical change from point A =
`y_2 - y_1 = 2 - 1 = 1`

Horizontal change from point A =
`x_2 - x_1 = 4 - 2 = 2`

Rate of change =
`(y_2 - y_1)/(x_2 - x_1) = (1)/(2) = 0.5`
